Chapter 21: RMON Configuration Guide
RMON Groups
The RMON MIB groups are defined in RFCs 1757 (RMON 1) and 2021 (RMON 2). On the
SSR, you can configure one or more levels of RMON support for a set of ports. Each
level—Lite, Standard, or Professional—enables different sets of RMON groups (described
later in this section). You need to configure at least one level before you can enable RMON
on the SSR.
To specify the support level for RMON groups, use the following CLI command line in
Configure mode:
To specify the ports on which RMON is to be enabled, use the following CLI command
line in Configure mode:
You can configure each level of RMON support independently of each other with default
tables on or off. For example, you can configure Lite with default tables on for ports
et.1.(1-8) and then configure Standard with no default tables for the same ports. You
cannot configure Lite on one set of ports and Standard on another set of ports.
Lite RMON Groups
This section describes the RMON groups that are enabled when you specify the Lite
support level. The Lite RMON groups are shown in the table below.
